Parent-child interaction: A micro-level sequential approach in children with a significant cognitive and motor developmental delay.

Background & aims: Previous research indicates that young children with a significant cognitive and motor developmental delay show low levels of interactive engagement, their parents are generally responsive towards them and these variables are positively correlated. Adapting a micro-level approach, we aim to go beyond macro-level and correlational analyses by charting the frequency, intra-individual co-occurrence and inter-individual temporal dependency of specific interactive behaviors. Methods & procedures: Twenty-nine parent-child dyads (with children aged 6-59 months) were video-taped during a 15-minute unstructured play situation. Based on a self-developed coding scheme, interactive behaviors were coded continuously and analyzed using a three-step sequential analysis approach. Outcomes & results: Parents and children systematically combine either more socially-oriented or more object-oriented behaviors. Socially-oriented behaviors are less frequent in children, especially looking at and touching the partner occurs less. Socially-and object-oriented behavioral clusters are generally independent from each other and instigate/maintain the same type of behaviors in the interaction partner. While children's socially oriented behavior(al cluster)s seem to need a parental 'trigger', parents will more often independently engage with their child despite low child responsiveness. Conclusions and implications: Further intervention-oriented research is needed to confirm this study's results and translate them into concrete guidelines for parents.
